IMO this is the real problem - and it comes through in your blog posts. It's very risky to hire someone who can't be a cog, you need a lot of social proof that they're worth the risk.
Edit: From what others wrote about about your blogs, I think your ascertion that your personal views shouldn't pose a proboem are wrong. By that I don't mean having them is wrong, but being as outspoken about, lets put it mildly, potentionally controversial opinions in a borderline aggressive way is the problem. It would be an equal problem if we talked veganism as another, potentionally bad, example. Nobody wants to be called out by their co-worker during lunch for having a steak everytime. And nobody wants to talk about why a co-worker feels insulted for not being ablento bring a gun to the workplace.
Edit 2: Paul Graham has one of his earlier articles that seems relevant: the one about keeping a low public profile. Is more relevant than ever, the more said profile deviates from the mainstream the more it can become a problem. GP is great example for this.
